Hello,
after a long time I have to say at first thank you very much for your nice comments!
I was a bit out of ideas here, so I have done another
small project, was busy with other things and finally something, which have to kept non-public until December (stay tuned!) but now I'm back here.
Alu metal plateWith handling of the fuselage the bonding opened a bit, so I take the chance and added some sheet. Now it is wider and has a bit more space for the engine.

With a back side of a brush I formed aluminium from grilling tray into a bonnet prototype. The resin part of the kit was to thick and flat. Not bad so far, only very thin on the top.

If aluminium bonnet, what about the rest? I have to rework the sides anyway, because this are not bolts from a tank, this is an aircraft!

Top and sides are done.

The top plate was hard to done, but then I detected on pictures from Hendon a second plate just in front of the cockpit. That way it works!

You can see small rivets on the pictures. Those are brass ones: 0,3 with 0,5mm head and 0,2 with 0,3mm head.
I tinned them prior cutting and mounting, which take a lot of time!

The front is mounted and the crossing to the lower side was rounded.

Front and lower side is a one piece:

Drilled from both sides of the engine, for a new longer axle for engine, both bearings and airscrew.

All plugged together for testing purposes.

And with the bonnet:

That was a lot of work, but sheet of real metal looks best like sheet of metal!
Cheers,
Frank
